Electroplated coatings are applied to steel for corrosion resistance, appearance, solderability, or other special requirements. A wide variety of materials are electroplated on steel, including nickel, chromium, zinc, cadmium, and tin. Multilayer coatings can also be applied by electroplating; an example is the copper-nickel-chromium plating system used for bright automotive trim. This section will review some of the more widely used electroplating processes for steels. More detailed information on each of the processes described below can be found in the articles contained in the Section entitled "Plating and Electroplating" in this Volume.
